Chemistry - Coordination Chemistry Question with Solution | TestHub

The question asks to choose the correct pair of central atom/ion and ligand for "the above mentioned complex". However, the complex itself is not provided in the question context. Without the specific complex, it is impossible to definitively determine the correct central atom/ion and ligand.

Assuming the question refers to a general understanding of common coordination complexes:

A. ${\mathrm{Fe}}^{2+}$ and ${\mathrm{NH}}_3$ are common in complexes like $[\mathrm{Fe}({\mathrm{NH}}_3{)}_6{]}^{2+}$.

C. ${\mathrm{Fe}}^{3+}$ and ${\mathrm{F}}^{-}$ are common in complexes like $[{\mathrm{FeF}}_6{]}^{3-}$.

Both options A and C represent valid central atom/ion and ligand pairs found in coordination chemistry. Without the specific complex, both are plausible.
